#40 – Omega 3 and Mental Health, Nutritional Psychology, the Protein Ammonia Link, Lectin, Mycotoxins and More With Kristin Kirkpatrick, RD

Many of us know firsthand that there is a significant link between the foods we eat and our mental health. Whether it’s a food sensitivity, nutrient deficiency, or just loading up on too much of a good thing, a growing body of scientific data teaches us that food and mood are connected. The field of nutritional psychology explores how nutritional inputs change symptoms of depression, anxiety, and other common problems we face in our fast paced lives. In today’s show, we are joined by Gene Food’s Chief Nutrition Officer, Kristin Kirkpatrick, RD, to discuss the latest research on eating for mental health. Of particular interest to many of our listeners will be research on omega 3 intake for the treatment of depression, as well as how the microbiome shapes the chemistry of our brains, including how we make serotonin.
